End IP Address
: The last IP address in the range that can be used to automati-
cally assign IP addresses to LAN hosts.
Subnet Mask
: A mask used to determine to what subnet an IP address belongs.
An example of a subnet mask value is 255.255.255.0.
Lease Time In Minutes
: Each device will be assigned an IP address by the
DHCP server for this amount of time, when it connects to the network. When
the lease expires the server will determine if the computer has disconnected
from the network. If it has, the server may reassign this IP address to a newly-
connected computer. This feature ensures that IP addresses that are not in use
will become available for other computers on the network.
Provide Host Name if Not Specified by Client
: If the DHCP client does not have
a host name, the gateway will automatically assign one for him.
DHCP Relay.
Your gateway can act as a DHCP relay in case you would like to
dynamically assign IP addresses from a DHCP server other than your gate-
way's DHCP server. Note that when selecting this option you must also change
Router's WAN to work in routing mode.
1.
After selecting 'DHCP Relay' from the drop down menu, a 'New IP Address'
link will appear: Click the 'New IP Address' link. The 'DHCP Relay Server
Address' screen will appear.
2.
Specify the IP address of the DHCP server.
3.
Click 'OK' to save the settings.
Disabled.
Select 'Disabled' from the combo-box if you would like to statically
assign IP addresses to your network computers.
LAN BRIDGE >> ROUTING
You can choose to setup your gateway to use static or dynamic routing. Dy-
namic routing automatically adjusts how packets travel on the network, whereas
static routing specifies a fixed routing path to neighboring destinations.

Routing Mode.
Select one of the following routing modes:
Route: Use route mode if you want your gateway to function as a router be-
tween two networks.
NAPT: Network Address and Port Translation (NAPT) refers to network ad-
dress translation involving the mapping of port numbers, allowing multiple
machines to share a single IP address. Use NAPT if your LAN encompasses
multiple devices, a topology that necessitates port translation in addition to
address translation.
Device Metric.
The device metric is a value used by the gateway to determine
whether one route is superior to another, considering parameters such as
bandwidth, delay, and more.
Default Route.
Select this check box to define this device as a the default
route.
Multicast - IGMP Proxy Internal.
IGMP proxy enables the system to issue
IGMP host messages on behalf of hosts that the system discovered through
standard IGMP interfaces. IGMP proxy enables the routing of multicast packets
according to the IGMP requests of LAN devices asking to join multicast groups.
Select the 'Multicast IGMP Proxy Internal' check-box to enable this feature.
IGMP Query Version.
If “
Multicast – IGMP Proxy Internal
” is enabled, this list
box allows you to select all three versions of supported IGMP.

Routing Information Protocol (RIP).
Select this check box to enable the Rout-
ing Information Protocol (RIP). RIP determines a route based on the smallest
hop count between source and destination. When RIP is enabled, select the fol-
lowing:
Listen to RIP messages - select 'None', 'RIPv1', 'RIPv2' or 'RIPv1/2'.
Send RIP messages - select 'None', 'RIPv1', 'RIPv2-broadcast' or 'RIPv2-
multicast'.
Routing Table.
Allows you to add or modify routes when this device is active.
Use the 'New Route' button to add a route or edit existing routes.
LAN BRIDGE >> BRIDGING
This section allows you to specify the devices that you would like to join under
the network bridge. Click the 'Edit' icon on the VLAN column to assign the net-
work connections to specific virtual LANS.

Select the 'STP' check box to enable the Spanning Tree Protocol on the device.
You should use this to ensure that there are no loops in your network configura-
tion, and apply these settings in case your network consists of multiple
switches, or other bridges apart from those created by the gateway.

ADVANCED
Internet Connection Firewall.
Your gateway's firewall helps protect your com-
puter by preventing unauthorized users from gaining access to it through a net-
work such as the Internet. The firewall can be activated per network connection.
To enable the firewall on this network connection, select the 'Enabled' check
box.

Additional IP Addresses.
You can add alias names (additional IP addresses)
to the gateway by clicking the 'New IP Address' link. This enables you to access
the gateway using these aliases in addition to the 192.168.1.1
LAN ETHERNET
A LAN Ethernet connection connects computers to the Router using Ethernet
cables.
LAN ETHERNET >>
GENERAL
To view and edit the LAN Ethernet connection settings, click the 'LAN Ethernet'
link in the 'Network Connections' screen. The 'LAN Ethernet Properties' screen
will appear, displaying a detailed summary of the connection's parameters, un-
der the 'General' tab. These parameters can be edited in the rest of the screen's
tabs, as described in the following sections.

SETTINGS
General.
This section displays the connection's general parameters. It is re-
commended not to change the default values unless familiar with the network-
ing concepts they represent. Since your gateway is configured to operate with
the default values, no parameter modification is necessary.
